Description

[Detailed Description of the Invention] The present invention relates to a fixing device for a heat insulating material used in a cooking device.

In a heating cooker, a heat insulating material 2 is installed on the top surface of the cooking chamber 1 as shown in Fig. 1 for the purpose of keeping the cooking chamber warm.
use. Conventionally, the heat insulating material 2 has been fixed to the top surface of the cooking cabinet with adhesive. Since the cooking chamber 1 is at a high temperature, it is necessary to use an inorganic adhesive as the above adhesive, but the adhesive currently used is expensive and only available in cans, so use a spatula or the like. Currently, it is applied to the adhesive surface, which is extremely inefficient for mass production.

By the way, in the heating cooker, control devices such as a time switch and a temperature regulator are used and are housed in a machine room provided on the side of the cooking cabinet 1. However, since the cooking chamber 1 is at a high temperature, the temperature inside the machine room increases, which adversely affects the characteristics and life of the control device.

Therefore, conventionally, as shown in FIG. 1, a metal plate 3 is provided to partition the upper space of the cooking cabinet 1 and the machine room to prevent the temperature rise in the machine room. Therefore, in the past, the metal plate 3 was provided with a cut and raised cut 4 as shown in FIG. 2, thereby fixing the heat insulating material 2. In such a configuration, by providing the cut and raised portions 4, holes are formed in the metal plate 3, reducing the effectiveness of the metal plate.

On the other hand, in the case where the metal plate 3 is not used, a metal fitting for fixing the heat insulating material is attached to the cooking cabinet, thereby fixing the heat insulating material. Such a configuration requires a mold for manufacturing the metal fittings, which is expensive.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to eliminate the above-mentioned conventional drawbacks and provide a cooking device that is less expensive and has good workability during manufacturing.

Embodiments of the present invention will be described below based on the drawings. In FIG. 3, which is a sectional view taken along the line A-A in FIG. 1, the metal plate 3 has a flange C portion provided in a direction opposite to a flange B portion fixed to a flange 5 provided on the upper surface of the cooking cabinet. The elastic heat insulating material 2 is sandwiched between the top surface of the cooking chamber and the flange C portion,
At the same time that the metal plate 3 is fixed to the flange 5 provided on the upper surface of the cooking chamber with screws 6, the heat insulating material 2 is also fixed.

This configuration eliminates the need for adhesives and metal fittings for fixing the heat insulating material, resulting in low cost. Since the metal plate 3 has a second flange in the opposite direction to the fixing flange, it has high independence, so during installation work, place the heat insulator 2 on top of the cooking cabinet 1 and place the metal plate 3 on top of it. There is no need to support it with your hands and you can fix it with screws, so you can use both hands freely and it is easy to work. In addition, there is no need to dry the adhesive and there is no need to attach metal fittings for fixing the heat insulating material, resulting in good productivity.

On the other hand, the role of the metal plate 3 is to prevent hot air from the upper space of the cooking cabinet from entering the machine room by partitioning the upper space of the cooking cabinet from the machine room. Therefore, by adopting the above-mentioned configuration, the airtightness between the upper surface of the cooking chamber and the metal plate 3 is improved, and the role of the metal plate 3 becomes even more effective.

In addition, it is possible to sufficiently press down the heat insulating material 2, making it difficult to create a space between the upper surface of the cooking cabinet and the heat insulating material 2, thereby improving the heat retention effect of the heat insulating material.

As explained above, this invention uses a second flange installed in the opposite direction to the fixing flange of the metal plate that partitions the upper space of the cooking cabinet and the machine room to sandwich the insulation material only by applying force from above. With the simple structure of inserting and fixing, it is possible to provide a heating cooker that is cheaper, has better productivity, and has improved performance.
